fix: use text() for SQLAlchemy 2.0 compatibility in pre_deploy.sh

[cfsmp3]

Summary

• Fix SQLAlchemy 2.0 compatibility issue in install/deploy/pre_deploy.sh
• The database connection test was using raw SQL strings (conn.execute('SELECT 1')), which is not supported in SQLAlchemy 2.0

Problem

After the SQLAlchemy 2.0 upgrade (commit fb0a5c5 on Jan 4), all deployments have been failing with:

Database connection FAILED: Not an executable object: 'SELECT 1'

This left 6 commits undeployed on the production server, including critical fixes like d316b61 (verify GCP VM creation).

Fix

Use text() wrapper as required by SQLAlchemy 2.0:

from sqlalchemy import create_engine, text
conn.execute(text('SELECT 1'))

Test plan

• After merging, manually apply the same fix to the server's pre_deploy.sh
• Trigger deployment via workflow_dispatch
• Verify deployment succeeds and server is updated to latest master
